Problems solved by technology

The traditional identification method is to determine the sex type of bitter gourd after at least 2 years of planting observation, which takes a long time and is easily affected by strong females and false all-female lines, which hinders the selection process of all-female lines of bitter gourd

Embodiment 1

[0026] A method for selecting and breeding all female lines of balsam pear, comprising the following steps:

[0027] (1) use bitter gourd all-female line MC39-36 to carry out crossing with MC39-34, obtain hybrid F 1 ;

[0028] (2) by crossing F 1 Backcross with MC39-34 to obtain backcross generation BC 1 f 1 ;

[0029] (3) planting BC 1 f 1 , all the individual plants are self-crossed and backcrossed with MC39-34 at the same time, and the corresponding numbers are made, and the BCs are harvested from each plant and single melon 1 f 2 and BC 2 f 1 ;

[0030] (4) planting BC 1 f 2 , 15-20 days before the flower buds appeared, silver nitrate treatment was carried out to induce males, and the corresponding BCs with hermaphrodite flowers were planted to induce males. 2 f 1 For the plants, choose a single plant with good agronomic characteristics for selfing, and at the same time backcross with MC39-34, make a corresponding number, and harvest BC for each plant and sin...

Abstract

The invention belongs to the technical field of all-female line breeding of bitter gourds, and specifically relates to a selection method of all-female lines of fine-variety bitter gourds. According to the selection method of the all-female lines of fine-variety bitter gourds, all-female materials of bitter gourds are utilized; and then, continuous back-crosses are performed so as to transform all-female genes of bitter gourds into materials to be improved, so that fine-variety all-female lines of bitter gourds are developed. Treated by utilizing silver nitrate, the all-female bitter gourd plants show the regularity of female flowers to hermaphrodite flowers to female flowers; and thus, interference from predominately gynoecious plants and fake all-female plants is avoided. Used as femaleparents, the bitter gourd all-female lines prepared by the method do not require castration for producing hybrids; and thus, hybrids with high purity can be produced with seed preparation efficiency improved and costs saved.

Description

technical field [0001] The invention belongs to the technical field of breeding of all-female lines of bitter gourd, and in particular relates to a method for breeding excellent all-female lines of bitter gourd. Background technique [0002] Bitter melon is generally a dioecious type, and there are also all female types. In the production of bitter gourd hybrids, the traditional method is to use the dioecious type as the female parent. During the hybridization, a lot of cumbersome work such as emasculation, bagging and isolation of female flowers, artificial pollination and marking of pollinated flowers is required, and the labor cost is high. The purity of the hybrids of bitter gourd cannot be fully guaranteed; using the all-female line of bitter gourd as the female parent does not require emasculation when producing hybrids, which can produce high-purity hybrids, improve seed production efficiency, and save costs. However, the traits of most all-female lines of bitter gou...
